As with tuning snares and bass drums, tuning your toms comes down to personal taste. What works best for me is as follows.

I tune the batter head first and I tune for the best sound of the drum rather than a certain note. I criss cross to each lug as I tension and press my thumb approximately 1'' in from the lug as I tune, making sure each has the same tension. I then tap approximately 1'' in from each lug with a stick, tweaking the lugs until each has the same tone.

I then strike the drum in the centre and fine tune for the desired sound.

I tune the bottom head the same tension, repeating as above.

Some drummers have their bottom heads slightly tighter or visa versa. Experiment and find what's best for you.

After I have repeated the above on each drum, I play a simple roll from highest to lowest tom. I make sure the toms are evenly spaced in sound, high to low. I then fine tune to the desired sound and repeat the tapping in 1'' from each lug process.

I like my drums to have a nice singing tone to them. If there is a nasty ring, it usually means a lug has incorrect tension. If all lugs are even and there is still a ring, I may resort to placing a little gaffa tape on the drum in question, but only as a last resort. Many drummers I speak to refuse to use any dampening whatsoever on their toms or snare drum.
